DNF Update Information - Fedora/CentOS 8

The Fedora operating system comes with an updated version of the famous yum package management utility, called “DNF”. DNF stands for “Dandified YUM”, and it retains the general syntax that users of the yum package manager are used to. If you are reading this post should be familiar with at least the basics of installing and updating packages with YUM or DNF. Take a look at the Fedora Docs if you need a quick refresher on how to install packages with DNF.

Git with the program

TLDR; git is awesome. It will save you time, and headaches if you are working on automation. Recently I’ve put some serious effort into learning and using git for version control. I know what you’re thinking…. probably something like “Just now learning git? Have you been living under a rock?”… I realize that I’m at least 10 years late to this party I just didn’t know what I was missing.

Enable http/2

The http 2.0 protocol is designed for increased speed and performance. The protocol was published for release in 2015 and is supported by Apache 2.4 using the mod_http2 module. Note: You will need to have a valid ssl cert for all practical purposes to implement http/2. Many web browsers including Firefox will not use http/2 on a site without an ssl cert. You can obtain a free ssl cert with letsencrpyt, check out https://certbot.

Upgrade to Fedora 30 Complete!

In the last couple of days there has been some extended downtime on this site. That is because I’ve been working on migrating my blog from Ubuntu 16.04 to Fedora 30. I’m switching for lots of reasons. Some of the php packages I need for Wordpress have been getting a bit out of date on Ubuntu 16.04 and I wanted to have the most up-to-date stable release of php without needing to add a third-party repository and Fedora 30 comes with php7.

Force Local Users and Groups with Ansible

I’m in the process of migrating a few Puppet modules over to Ansible, and in the process I’ve run into an unusual situation while creating users and groups. Here is some background. I have an application that will refuse to complete its installation unless it can see certain users and groups in the local passwd and group files. It just so happens that these same users and groups are also contained in LDAP.

Convert a pem file into a rsa private key

When you build a server in AWS one of the last steps is to either acknowledge that you have access to an existing pem file, or to create a new one to use when authenticating to your ec2 server. If you want to convert that file into an rsa key that you can use in an ssh config file, you can use this handy dandy openssl command string. openssl rsa -in somefile.
